Cheezburger Network grew to prominence by allowing its users to attach funny captions to dog and cat photos. But who says that captions should be limited to felines and canines? Continuing to expand its empire of comedy sites, Cheezburger introduced this week a new site called Just Capshunz.

And like the poorly-spelled name suggests, the site allows users to attach captions to a wide variety of photos.

“This new site brings you people, animals, places and things in all of their captioned glory,” the company writes in a description.

What does that mean?

Well, visitors to the site can check out funny photos and captions that include frogs in toy airplanes, baseball players screaming at umpires and, my personal favorite, a man trying to sneak a kiss from a polar bear.

Just Capshunz is one of about 50 sites in the Cheezburger empire, which continues to grow fast following its $30 million venture capital round from earlier this year. Cheezburger says its sites now attract 19.1 million visitors per month. The profitable company, led by Ben and Emily Huh, acquired the Know Your Meme site in March and rolled out its official iPhone app last month.
